Can somebody tell me what's the difference between these grommets (e.g. cushion rings)? The description calls one an upper and one a lower grommet. I'm only familiar with one - the one where the injector mounts to the rail. Here's the link to the description... GROMMETS Thanks, -john

Here is a pic of a beck arnley injector seal kit. It has 2 cushions.

(from NAPA web site)

Thanks Yoda. I can't find that seal set on Beck-Arnley. Can you tell me how you located it? I see a "Injectors and Seals" but none of them are just seals by themselves.
Thanks,

Its got two on the top of the injector, the small o-ring that actually seals the high pressure fuel and then the upper grommet (on the right in the pic above). Then there is the lower grommet (the lowest one in the pic above) the seals the injector to the intake manifold to prevent a vaccume leak. Not real sure about the largest o-ring in the pic above (on the left)

the BA # on the napa web site is 1580090

Don't know if the link will work, but here goes:

The NAPA kit has even more seals (the CRB # 212080)

Here's what I used on my last injector project (Toyota P/N's, listed from top to bottom, I think):
O-Rings (top): 90301-07001
Grommets (top): 90480-13005
Injector Insulator (bottom, on top of spacer?): 23291-41010
Spacers (bottom, on intake manifold): 90561-10002
Spacer O-Rings (bottom, on spacer): 90301-23004

Don't freak out when you pull the old lower insulator off and it looks nothing like what you have to replace it with. That lower insulator bakes and changes shape BIG time once you have 150k on the motor. The guy at the dealer was laughing when I handed him an old one and said "I just cant find the right ones" and he explained that to me.

The smallest o-rings goes at the top of the injector. The largest around the outside of the bakelite insulator that the injector sits in. The right grommet slips over the top of the injector & pushes down to where it flares out. The lower left grommet goes on the very botton of the injector. Did they look like this when you pulled them out?



IMHO, send them away & have the completely redone for only @ $13 each; I spent more than that on seals/o-rings alone!
